Kathryn A Patras, Kelly S Doran
Streptococcus agalactiae (group B Streptococcus, GBS), is a Gram-positive, asymptomatic colonizer of the human gastrointestinal tract and vaginal tract of 10 - 30% of adults. In immune-compromised individuals, including neonates, pregnant women, and the elderly, GBS may switch to an invasive pathogen causing sepsis, arthritis, pneumonia, and meningitis. Because GBS is a leading bacterial pathogen of neonates, current prophylaxis is comprised of late gestation screening for GBS vaginal colonization and subsequent peripartum antibiotic treatment of GBS-positive mothers...

Group B Streptococcus (GBS) is a major cause of neonatal sepsis and mortality worldwide. Studies from both developed and developing countries have shown that HIV-exposed but uninfected (HEU) infants are at increased risk of infectious morbidity, as compared to HIV-unexposed uninfected infants (HUU). A higher susceptibility to GBS infections has been reported in HEU infants, particularly late-onset diseases and more severe manifestations of GBS diseases. We review here the possible explanations for increased susceptibility to GBS infection...

Posterior reversible encephalopathy syndrome (PRES) is an unusual disease of unknown incidence and cause. There are a wide range of associated, predisposing medical causes to include pregnancy, renal failure, immunosuppressive medication administration and hypertension. The diagnosis is made following the radiographic identification of characteristic vasogenic edema in the setting of neurologic impairment. A significant portion of patients will have long-term, if not permanent, sequelae of the disease. We present a patient who developed PRES following a hemicolectomy that was complicated by an anastomotic leak...

INTRODUCTION: Neonatal respiratory distress (NRD) is a main cause of neonatal morbidity and mortality in developing countries. Early detection of its risk factors and early treatment of its etiologies are major challenges. However, few studies in developing countries have provided data needed to tackle it. We aimed to determine the prevalence, predictors, etiologies and outcome of NRD in a tertiary health care centre of Cameroon. METHODS: We analyzed the hospital files of all newborns admitted to the Neonatal unit of Douala General Hospital from 1(st) January 2011 to 28(th) February 2013...

BACKGROUND: Patients with sepsis commonly exhibit a hypercoagulability with high risk of venous thromboembolism (VTE). Neutrophil extracellular traps (NETs) are found to trigger inflammation and coagulation. We aim to determine whether NETs promoted the hypercoagulability and early anticoagulation reduced NETs releasing during sepsis. METHODS: In this prospective study, septic patients between September 2013 and June 2015 were included. Patients of age < 18 years, acute organ failure, pregnancy, coagulation disorders, receiving anticoagulation before admission were excluded...

Generalized pustular psoriasis of pregnancy is a rare dermatosis with potential serious consequences for both the mother and fetus. Treatment is difficult and historically steroids were the mainstay of treatment. Cyclosporin has been used for a few cases resistant to steroids. We report our own experience of two cases of generalized pustular psoriasis of pregnancy. Cases of generalized pustular psoriasis of pregnancy need review by a dermatologist with experience of skin disorders in pregnancy. Both the fetus and mother need to be monitored closely when systemic illness occurs, as there is a risk of stillbirth...

BACKGROUND: The incidence of type 2 diabetes in pregnancy is rising and rates of serious adverse maternal and fetal outcomes remain high. Metformin is a biguanide that is used as first-line treatment for non-pregnant patients with type 2 diabetes. We hypothesize that metformin use in pregnancy, as an adjunct to insulin, will decrease adverse outcomes by reducing maternal hyperglycemia, maternal insulin doses, maternal weight gain and gestational hypertension/pre-eclampsia. In addition, since metformin crosses the placenta, metformin treatment of the fetus may have a direct beneficial effect on neonatal outcomes...

BACKGROUND: Maternal mortality is of global public health concern and >99 % of maternal deaths occur in less developed countries. The common causes of direct maternal death are hemorrhage, sepsis and pre-eclampsia/eclampsia. In Pakistan, pre-eclampsia/eclampsia deaths represents one-third of maternal deaths reported at the tertiary care hospital settings. This study explored community perceptions, and traditional management practices about pre-eclampsia/eclampsia. METHODS: A qualitative study was conducted in Sindh Province of Pakistan from February to July 2012...

BACKGROUND: Post-caesarean section infection is a cause of maternal morbidity and mortality. Administration of antibiotic prophylaxis is recommended for preventing infection after caesarean delivery. The route of administration of antibiotic prophylaxis should be effective, safe and convenient. Currently, there is a lack of synthesised evidence regarding the benefits and harms of different routes of antibiotic prophylaxis for preventing infection after caesarean section. OBJECTIVES: The aim of this review was to assess the benefits and harms of different routes of prophylactic antibiotics given for preventing infectious morbidity in women undergoing caesarean section...

There has been an increasing incidence worldwide of invasive group A streptococcal disease in pregnancy and the puerperal period over the past 30 years. Group A Streptococcus (GAS) was identified as the major cause of maternal morbidity and mortality from sepsis before the identification that hand washing techniques could prevent the transmission of the bacteria. Hand washing remains the cornerstone of prevention as transmission can occur directly from an asymptomatic colonized healthcare provider, other patients, or a community-acquired source...

Ovarian vein thrombosis is a rare, but potentially serious postpartum complication. In 80% of the cases, it occurs on the right side and in less than 6% on the left side; it is bilateral in 14% of cases. The usual clinical features include abdominal pain, fever and leucocytosis. However, the diagnosis is often complicated by other non specific signs and symptoms. Ovarian vein thrombosis may cause sepsis, pulmonary thromboembolism, and thrombosis of the inferior vena cava and the renal vein. The diagnosis can be established by CT scan or nuclear magnetic resonance imaging, which has a high sensitivity and specificity...

BACKGROUND: Vasa previa is a rare condition that is associated with a high rate of fetal or neonatal death when not diagnosed antenatally. The majority of available studies are either small, do not include antepartum data, limited to single institutions, or are biased by inclusion of patients from registries and online vasa previa support groups. OBJECTIVE: The purpose of this study was to investigate the diagnostic and management strategies for this potentially catastrophic entity and to describe further maternal and placental risk factors that may aid in the establishment of a screening protocol for vasa previa...
